DARNING-MACHINE.

SPECIFICATION forming part of Letters Patent l\ T0. 724,783, dated April 7, 1903.

'Application filed November 28, 1902. Serial N01 133,066. (No model.)

To all whom it may concern."

Be itknown that I, FRANQOIS BELANGER, a citizen of the United States, residing at Langdon, in the county of Cavalier'and State of North Dakota, have invented new and useful Improvements in Darning-Machines,of which the following is a specification.

This invention relates to darning-machines; and the object thereof is to provide a cheap,

durable, and efficient device for repairing rents, tears, or holes in fabrics.

The peculiar manner of accomplishing the desired result, as well as the novel details of construction, will be specifically referred to hereinafter and illustrated in the accompanying drawings, in which-- Figure 1 is a top plan view of a darningmachine, showing the shifting hooks in one position. Fig. 2 is a similar View showing the hooks reversed. Fig. 3 is a vertical longitudinal sectional view through the darningmachine, and Fig. 4 is a cross-sectional view on the line 4 4 of Fig. 3.

The frame of the machine consists of two side bars 1 and 2, connected at their top by a base-plate 3, having a rectangular slot or cut-out portion 4 therein,on one edge of which are upwardly-projecting hooks 5. On the opposite end of theframe and secured in journals 6 and 7 are the rocking shifting hooks 8,

' which are provided with intermediate cranks 9, adapted to be simultaneouslyoperated by a shifting bar 10, whioh is connected to the crank and'between the ends of which is a ring 11. The hooks 8 are provided with notches 12, into which the thread or yarn is to pass, and the ends of the hooks are provided with grooves -13, which are designed to aline when the same are in a position shown in Figs. 1 or 2, so that the needle will pass in the grooves of the respective hooks and thereby be guided between the strands of yarn.

On one end of the frame is 'a downwardly-.

in proper engagement with relation to the frame. This jaw lfi'will' clamp the material to the frame, so that it will be held taut across the slot formed in the plate 3. In forming the warp a strand of the darning material will be passed alternately from the hooks 5 to the hooks 8 back and forth, as

shown in Figs. 1 and 2, and the end fastened conveniently to oneof the hooks. The woof will be passedback and forth through thestrands, the needle being passed through the grooves in the ends of the hooks until the thread is carried entirely across the machine. The shifting bar 10 can be controlled, so as to reverse the position of the hooks, whereby the lower strands of the warp become the upper ones. In operating the machine the second and third fingers are placed beneath the clamping-jaw, so as to bear against the un= der side of the plate 17. The little finger and index-finger engage the sides of the flanges 1 and 2, while the thumb is passed through the ring 11. By moving the thumb from right to left or transversely of the frame the hooks can be shifted from one side to the other. This will cause the loops forming the warp to alternately become the top and bottom strands. In placing the warp in proper relation to the frame the cranks will be moved on a vertical plane, as shown in Fig. 3, but as soon as the strand is in proper position they will be moved either. to the right or to the left, as shown in Figs 1 and 2, and

the woof will be interwoven between them.

By releasing the jaw the material can be removed. After the fabric is suitably darned thej'aw 16 can be released and the material taken out.

Having thus described-my invention, what I claim, and desire to secure by Letters Patout, is

1. A damning-machine comprising a plate having a slot therein, of rigid hooks formed on the plate at one edge of the slot, reversible hooks on the opposite side of the slot and alternating with the rigid hooks, cranks formed integral with the reversible hooks and intermediate the ends thereof, and a shifting bar connecting the cranks so as to operate the hooks simultaneously.

2'. A darning-machine comprising a plate cranks and a ring intermediate the ends of having a slot therein, of rigid hooks formed the bar for the purpose set forth. to on the plate at one edge of the slot, reversing- In testimony whereof I affix my signature hooks on the opposite edge of the slot, cranks in presence of two witnesses.

5 formed integral with the reversing-hooks and I FRANCOIS BELANGER.

intermediate the ends thereof, the respective Witnesses: ends of each of the cranks being journaled in t H. W. MONTGOMERY,

the frame, a shifting bar connected to the W. F. LAVIN.
